Neoplasia said:They like it stable. You can forget about "optimal" pH levels, the best thing to do is keep it at the level that the tank tries to be at, unless it is to one extreme or another. Optimal pH is going to require a lot of fiddling and if you're not careful you can stress out your fish. And they also don't need it to be "optimal", stability is by far more important.
Adicedic PH of 5 or 6??? Where and who told you that?!?!?!memen said:piranhas prefer a acidic Ph like 5 at 6,5, and like allother amazonian species fish
7 is not the better but they cn stay alive. ::
Add crushed coral or filter media designed for East-African cichlid (which require hard water) tanks to your canister filter.....Croz said:what can you do to raise pH ?
True, even though your PH levels might not even be close to normal or perfect, as long as your fish have adapted to the perimeters, then there is no other reason to tamper with it.lastyboy said:if it aint broke, dont fix it!!
